2. Description of Related Art

In recent years, with the popularity of mobile products having camerafunctionalities, the demand of miniaturized optical systems has beenincreasing. The sensor of a conventional optical system is typically aCCD (Charge-Coupled Device) or a CMOS (ComplementaryMetal-Oxide-Semiconductor) sensor. As the advanced semiconductormanufacturing technologies have allowed the pixel size of sensors to bereduced and compact optical systems have gradually evolved toward thefield of higher megapixels, there is an increasing demand for compactoptical systems featuring better image quality.

A conventional optical system employed in a portable electronic productmainly adopts a four-element lens structure or a five-element lensstructure. Due to the popularity of mobile products with high-endspecifications, such as smart phones and tablet personal computers, therequirements for high resolution and image quality of present compactoptical systems increase significantly. However, the conventionaloptical systems cannot satisfy these requirements of the compact opticalsystems.

Other conventional compact optical systems with six-element lensstructure enhance image quality and resolution. However, the axialdistance between the first lens element and the second lens elementtends to cause problems in assembling since the axial distance betweenthe first lens element and the second lens element is rather small.Accordingly, it is not favorable for being applied to compact electronicproducts. Moreover, the unfavorable arrangement of the refractive powerof the second lens element also leads to greater sensitivity whichthereby causes worse image quality.

DETAILED DESCRIPTION

An optical image capturing lens assembly includes, in order from anobject side to an image side, a first lens element, a second lenselement, a third lens element, a fourth lens element, a fifth lenselement, and a sixth lens element. The optical image capturing lensassembly has a total of six lens elements with refractive power and canfurther include a stop and an image sensor, wherein the stop is locatedbetween an imaged object and the second lens element, and the imagesensor is located on an image plane side of the optical image capturinglens assembly. More specifically, the image sensor can be located on animage plane.

The first lens element with positive refractive power has an object-sidesurface being convex in a paraxial region thereof, so that the totaltrack length of the optical image capturing lens assembly can be reducedby properly adjusting the positive refractive power of the first lenselement.

The second lens element with negative refractive power has anobject-side surface being concave in a paraxial region thereof and animage-side surface being convex in a paraxial region thereof, so thatthe main refractive power of the optical image capturing lens assemblycan be more balanced so as to effectively reduce the tolerancesensitivity.

The third lens element with refractive power can have an object-sidesurface being convex in a paraxial region thereof and an image-sidesurface being concave in a paraxial region thereof, wherein theimage-side surface of the third lens element changes to a convex shapefrom the paraxial region thereof to an off-axis region thereof, orchanges to a convex shape and then to a concave shape from the paraxialregion thereof to the off-axis region thereof. Therefore, theastigmatism and the aberration of the off-axis can be corrected.

The fourth lens element with refractive power has an object-side surfacebeing convex in a paraxial region thereof and can have an image-sidesurface being concave in a paraxial region thereof. Therefore, theastigmatism can be further corrected.

The fifth lens element with positive refractive power can have anobject-side surface being concave in a paraxial region thereof, and hasan image-side surface being convex in a paraxial region thereof.Therefore, the sensitivity of the optical image capturing lens assemblycan be reduced effectively.

The sixth lens element can have negative refractive power and has animage-side surface being concave in a paraxial region thereof, whereinthe image-side surface of the sixth lens element has at least one convexshape in an off-axis region thereof. Therefore, the principal point ofthe optical image capturing lens assembly can be positioned away fromthe image plane, and the back focal length thereof can be reduced so asto maintain a compact size of the optical image capturing lens assembly.Furthermore, the incident angle of the off-axis on the image sensor canbe effectively reduced for increasing the responding efficiency of theimage sensor.

When a focal length of the optical image capturing lens assembly is f,and a curvature radius of the object-side surface of the fourth lenselement is R7, the following relationship is satisfied: 0.60<f/R7.Therefore, the astigmatism and spherical aberration of the optical imagecapturing lens assembly can be effectively corrected. Preferably, thefollowing relationship is satisfied: 0.6<f/R7<2.0.

When a curvature radius of the object-side surface of the second lenselement is R3, and a curvature radius of the image-side surface of thesecond lens element is R4, the following relationship is satisfied:(R3+R4)/(R3−R4)<−1.0. Therefore, the interference caused by the smalleraxial distances between lens elements during the assembling can beavoided, and the arrangement of the lens element is more applicable tocompact optical systems with strict space limitations. Preferably, thefollowing relationship is satisfied: −5.0<(R3+R4)/(R3−R4)<−1.0.

When a focal length of the fifth lens element is f5, and a focal lengthof the sixth lens element is f6, the following relationship issatisfied: −1.0<f6/f5<−0.5. Therefore, the distribution of therefractive power of the optical image capturing lens assembly can bebalanced for reducing the back focal length thereof so as to keep thecompact size of the optical image capturing lens assembly.

When an axial distance between the third lens element and the fourthlens element is T34, and an axial distance between the fourth lenselement and the fifth lens element is T45, the following relationship issatisfied: 0.05<T34/T45<0.35. Therefore, it is favorable for assemblingthe lens elements of the optical image capturing lens assembly so as toincrease the manufacturing yield rate.

When a distance in parallel with an optical axis from an axial vertex onthe image-side surface of the fifth lens element to a maximum effectivediameter position on the image-side surface of the fifth lens element isSag52, and a central thickness of the fifth lens element is CT5, thefollowing relationship is satisfied: 1.0<|Sag52|/CT5. Therefore, thesurface shape of the lens elements will not be excessively curved whichis favorable for manufacturing and molding the lens elements and keepingthe optical image capturing lens assembly more compact.

When a focal length of the third lens element is f3, and a focal lengthof the fourth lens element is f4, the following relationship issatisfied: −0.6<f4/f3<0.3. Therefore, it is favorable for reducing thephotosensitivity and correcting the aberration.

When a central thickness of the fifth lens element is CT5, and a centralthickness of the sixth lens element is CT6, the following relationshipis satisfied: 0.5<CT5/CT6<1.2. Therefore, it provides favorablemoldability and homogeneity for plastic lens elements during theinjection molding process.

When an Abbe number of the first lens element is V1, an Abbe number ofthe second lens element is V2, and an Abbe number of the third lenselement is V3, the following relationship is satisfied:0.6<(V2+V3)/V1<1.2. Therefore, the chromatic aberration of the opticalimage capturing lens assembly can be corrected.

When a maximum image height of the optical image capturing lens assembly(half of a diagonal length of an effective photosensitive area of theimage sensor) is ImgH, and an axial distance between the object-sidesurface of the first lens element and the image plane is TL, thefollowing relationship is satisfied: TL/ImgH<2.0. Therefore, it isfavorable for keeping the optical image capturing lens assembly compactso as to be applied to thin and portable electronic products.

According to the optical image capturing lens assembly of the presentdisclosure, at least two lens elements among the first through thefourth lens elements have at least one inflection point formed on atleast one of the object-side surface and the image-side surface thereof.Therefore, it is favorable for correcting the aberration of theoff-axis.

According to the optical image capturing lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive power of the optical image capturing lensassembly may be more flexible to design. When the lens elements are madeof plastic material, the manufacturing cost can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, because the aspheric surface of the lens element is easy toform a shape other than spherical surface so as to have morecontrollable variables for eliminating the aberration thereof, and tofurther decrease the required number of the lens elements. Therefore,the total track length of the optical image capturing lens assembly canalso be reduced.

According to the optical image capturing lens assembly of the presentdisclosure, an aperture stop can be configured as a front stop or amiddle stop. A front stop disposed between an imaged object and thefirst lens element can provide a longer distance between an exit pupilof the optical image capturing lens assembly and an image plane andthereby improves the image-sensing efficiency of an image sensor. Amiddle stop disposed between the first lens element and the image planeis favorable for enlarging the field of view of the optical imagecapturing lens assembly and thereby provides a wider field of view forthe same.

According to the optical image capturing lens assembly of the presentdisclosure, the optical image capturing lens assembly can include atleast one stop, such as an aperture stop, a glare stop or a field stop.Said glare stop or said field stop is for eliminating the stray lightand thereby improving the image resolution thereof.

According to the optical image capturing lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axis region. The paraxial region refers tothe region of the surface where light rays travel close to an opticalaxis, and the off-axis region refers to the region of the surface wherelight rays travel away from the optical axis. Particularly, when thelens element has a convex surface, it indicates that the surface isconvex in the paraxial region thereof; and when the lens element has aconcave surface, it indicates that the surface is concave in theparaxial region thereof.
